Without delay, let's solve this. We've got 581 and we will be multiplying it by 16, that is, adding 581 to itself 16 times.
Step 1: 0 + 581 = 581
Step 2: 581 + 581 = 1162
Step 3: 1162 + 581 = 1743
Step 4: 1743 + 581 = 2324
Step 5: 2324 + 581 = 2905
Step 6: 2905 + 581 = 3486
Step 7: 3486 + 581 = 4067
Step 8: 4067 + 581 = 4648
Step 9: 4648 + 581 = 5229
Step 10: 5229 + 581 = 5810
Step 11: 5810 + 581 = 6391
Step 12: 6391 + 581 = 6972
Step 13: 6972 + 581 = 7553
Step 14: 7553 + 581 = 8134
Step 15: 8134 + 581 = 8715
Step 16: 8715 + 581 = 9296

So, 581*16 = 9296
